Response of Broiler Chickens Fed Different Forms of Tanzania-type Diets with Microbial Enzymes

A study was conducted to assess the effect of feed form and microbial enzyme supplementation on performance, endogenous activities nutrient digestibility in broiler chickens fed Tanzania-type diets. total 480 day-old Ross 308 were allocated a 2 (mash or pellet) × 4 (no enzyme, Axtra XB, Quantum Blue XB + Blue) factorial arrangement, completely randomized design with 10 birds per replicate. Feed intake (FI), body weight gain (BWG) conversion ratio (FCR) determined at 10, 24 35 days age. Visceral organ measured d d, meat parts yield assessed d. (FI) highest pelleted diets it increased further when enzymes supplemented individually combination. Body comparatively higher Enzyme found increase BWG The FCR reduced compared mash-fed birds. Birds provided combination QB responded lower FCR. relative gizzard plus proventriculus, pancreas small intestine mash; however, only observed weights most (breast, thighs drumsticks) significantly inclusion enzymes. dry matter (DM) neither affected by nor while gross energy (GE), starch, protein, fat than those mash. Addition positively influenced all nutrients that assessed. Endogenous supplied diets, except for sucrase, which not form. Exogenous sucrase aminopeptidase results indicated both pelleting FI improved chickens. pancreatic jejunal feeding feeds, resulting better digestibility.
